Anna Sale here on the day shift.

We had a great conversation this morning about President Obama's charge to secure the world's nuclear material in four years, but we still have more questions. Which countries possess unsecured nuclear material? Where is that material located, which groups want to get their hands on it — and which groups already have their hands on it? We’re hoping to answer some of these questions with Sharon Squassoni, an expert on nuclear proliferation and prevention with the Center for Strategic and International Studies. And we’re on the hunt for an investigator who works to track down stolen nukes for some insight into what kind of detective work goes into finding and securing dangerous nuclear material.

The Colorado Attorney General told us last week that he considers the health care package an unconstitutional overreaching of federal powers. These calls for a militia take this a step farther. But not all Republicans in Oklahoma agree it's a good move. We'll talk to lawmakers about the debate in Oklahoma.
